Methods of synthesis of hybrid materials based on the sponge-like acetals of polyvinyl alcohol with the pore space which are partially impregnated by functional pH- and temperature-sensitive hydrogels (based on acrylic acid and N-isopropylacrylamide) have been developed, and their physicochemical properties (tensile strength and elasticity, sorption capacity, degree and rate of swelling) have been investigated. The synergistic improvement of properties of hybrid hydrogels in comparison with the components, from which they are constructed, is demonstrated, and the possibility of using these materials for the separation, removal, and concentration of dyes from polluted wastewaters is shown.
